This invention relates to a wiping device and, particularly, to such a device for cleaning continuous strip metal.

In the coldrolling of strip metal it is necessary that the strip be perfectly clean as it passes into and between the rolls of the mill. This is necessary in order to protect therolls and to preventl foreign matter, which may have collected on the through.

It is afurther object of the invention to provide a wiping device which can be used for cleaning strips of various thicknesses and one in which the desired pressure of the device on the strip can be adjusted. v

Various other objects and advantages of this invention will be more apparent in the course of the following specification and will be particularly pointed out in the appended claims.

In the accompanying drawings, there is shown', for the purpose of illustration, one embodiment which my invention may assume in practice.

In these drawings:

Figure 1 is a side elevation of a rolling mill,

partly in section, showing the improved wiping device of my invention assembled inoperable position thereon;

Figure 2 is a front elevationof the improved wiping device, showing it in its closed and operable'position; Y v

Figure 3 is a view similar to Figure 2, showing the wiping device in its open and inoperable position; and,

Figure 4 is a side view thereof. y Referring more particularly to the prises a supporting memberor base-plate 2 having a pair of upwardly extending posts-ory studs I arranged at each endv thereof. vEach of the posts Bhas a reduced upper threaded portion 4 providing a shoulder l intermediate the ends thereof.. The base 2 isl so constructed that it can drawings, the improved wiping device of Thy-invention comv 5 Claims. (Cl. 15---1 I)2)v .y

`tangular-shaped movable plates 6, each having a pad 1 arranged thereon. This pad preferably consists of a piece `of fabric wrapped several times around the plate, but it will be understood that any other suitable pad could vbe used. There is arranged on the posts 3 above the pad carrying plates l, a movable hold-down plate l. Above the hold-down plate l on the upper threaded portion of the posts or studs there is arranged a rectangularly plate-like ,member 9 which is 10 adapted to rest normally on the shoulders 5 of the posts. There is arranged adjacent the sides of the plate-like member il, upwardly extending flange portions 9, and there is arranged .therebetween in the plate-like member 9 a rectangu- 15 larly-shaped opening 9b. There is arranged on the threaded portion 4 of each of the posts 3 above the plate-like member 9 a coil spring Ill and anA adjusting nut I2 positioned thereabove.

The hold-down plate 8 carries spaced-apart 20 upwardly extending plates I3 which are adapted to extend up through .the rectangularly-shaped opening in the plate-like member 9. There is movably positioned between the upwardly extending plates I3 an actuating member I4 having 25 a handle portion I5. This actuating member I4 carries a pin I6, the ends of `which are adapted to. extend through vertically extending slotted holes I1 arranged in the vertical plates I3 and .through suitable holes positioned in the flanges 9 of the 30 plate-like member 9 to pivotally attach the actuating member I4 thereto.

The actuating member also carries a second pin I8, the ends of which are adapted to extend through curved or arcuate-shaped slotted holes 35 I9, also arranged in the vertically extending plates I3. There is also positioned on the actuating member I4 a suitable roller 20 suitably spaced from lthe pin I6 and which is adapted to cooperate with the top surface of the hold-down 40 plate l.

The improved wiping device of my invention operates as follows:

It will be assumed that the wiping device is in its open and inoperable position as shown in Flg- 45 ure 3. The metal strip is rSt threaded between ,the pads 1 into the rolling mill and .the wiping device is then ready to be set in operable position.' As the handle I5 of the actuating member I4 is moved downwardly about its pivotal connection, 50 namely, the pin I6 carried by the plate-like member 9, -the pin I8 carried by the actuating member I4 and disposed inthe arcuated slotted holes I! of the upwardly extending plate-like flanges Il carried by the hold-down plate 8 will follow 55 the path of the arcuated slotted holes I9, and the roller 20 arranged on fthe lower side of the actuating member I4 Will ride over the top of the hold-down plate 8 thereby forcing the same downwardly against the topmost pad 1, so as to force the pads together, as shown in Figure 2 of the drawings. It will thus be seen that in this position the hold-downplate 8 and the upper plate-like member 8 are then held in a spacedapart position from each other by the actuatingmember I4. It will be understood that the posts 3 act as a guiding means for both the wiping pads and the hold-down plate 8 in their movement.

In this closed position the plate-like member 9 is forced upwardly away from the shoulders 5 on the posts 3 against the action o! the coiled springs I0, so as to yieldably position the holddown plate 8 against the top pad 1 and thereby holding the pads yieldably in contact with the metal strip as it passes continuously between the pads. 'I'he amount of pressure that it is desired to exert by the pads against the metallic stripv can be adjusted by means of the adjusting nuts I2 on thetop of the posts.

To release the pressure on the wiping pads the handle I5 is moved upwardly about its pivotal connection, and the pin I8 carried by the actuating member I4 and disposed in the arcuated slotted holes I8 of the plate-like ilanges I3 carried by the hold-down plate 8, follows the slotted holes and forces the hold-down plate 8 upwardly due to a camming action out of contact with the topmost pad to a position as shown in Figure 3 of the drawings.

Asa result of my invention, it will be seen that .,a continuous strip'of metal can be effectively and efliciently cleaned and the device can be easily and quickly adjusted for any thickness ofV metal which is adapted to be cleaned. Also, after the pads 'I have worn out or possess no further cleaning properties, they can be easily removed and replaced with fresh pads.

While I have shown and described an embodiment of my invention, it will be understood that this embodiment is merely for the purpose of illustration and description and that various other forms may be devised within the scope oi' my invention, as deiined in the appended claims.

I claim:
